access to starter relay bauknecht 2209/a/1

[spikey1973]

Since a couple of days my old Bauknecht 2209/a/1 stopped cooling normally.
I say normally as when the compressor fires-up it works fine.

I figured out that, when I turn it off / unplug it for a minute or so,  it works but then when I shut it off
(or after the cooling cycle? just assuming dit not actually test this as such as I took the door off)
and it doesn't start up again, when it needs too. 

The only way tot get it going again is to turn it off  / on again, the internal switch in the thermostate does this fine enough.
When it doesn't I hear just a very light buzzing.  

Initually I felt like it was the thermostate, but now I feel it's more likely for the cause to be the capacitor.
The capacitor can't charge up enough unless the shut-off.

Ofcourse I need to test this, but to be able to do this I need to take the cap off, that is covering the starter relay.
Unfortunately I have no idea how to take this off without wracking it.

So it anyone can help me out here?

I would really appreciate it.

update:

I am not sure what I did, but i got the cap off trying around with a flathead screwdriver.So it was just clicked on.
to my surprise, I did NOT find a starter relay there, just a plastic block to connect the wiring to, but there has to be one, not?. Anyway, I tested the capacitor with my multimeter and measured 2.4uF.
This matches quite well with in the 2.5uF +/- 5% tolerance so it seems to be fine.
Which sounds nice, but now I need to figure out the real problem,
Can this be thermostate related, why would a thermostate work at one point and not right after?
Or is it the starter relay? and ifso, where it is located?

Hope, someone can help me with this new issue.
